The environmental "cold' damage in this area spams like crazy. Instead of 1 instance per round of damage, it does several instances (my one summon with 150 HP was brought down from full health to dead in under 4 minutes of being in there).

*edit: Checked the log..... the script was shooting off 16 instances of cold damage per round on me (checked by casting two spells in a row, no haste or quicken spell). When the skeletons respawned a moment later, the number of instances more than doubled.

Besides from serious damage spammage, it also seems to cause severe lag for the player at least to be in there.... not sure if it affects the rest of the server or not. My framerate dropped to practically a standstill, and my action commands were not activing until nearly a minute after I issued them.
